Abstract
L'invention concerne un procédé de récupération d'amines provenant de solutions acides de sel d'amine, par adjonction de bases et évaporation de la solution à un pH compris entre 11 et 13, dans un sécheur malaxeur, jusqu'à obtention d'un solide utilisable, sous forme de résidu de distillation. L'invention concerne également un dispositif de réduction de boues et de suspensions en un solide et une pluralité de fractions liquides séparées en fonction du point d'ébullition. La phase d'amine pauvre en eau séparée par distillation est déshydratée avec de l'oxyde de calcium ou de l'hydroxyde de potassium et est ensuite séparée par rectification en fractions d'amine pures. Ce procédé permet d'utiliser tous les flux secondaires et de recycler complètement les amines et l'absorbant (l'acide sulfurique). Les flux utilisés dans le processus de recyclage sont des acides de lavage chargés en amines, issus d'absorbants, obtenus pendant l'épuration de l'air d'évacuation contenant des amines, produit par ex. lors du processus cold-box utilisé pour le durcissement de sable à noyaux dans les fonderies.
